The Q&A Archives: Controlling Rust on Hollyhocks

Question: How can I control rust on my hollyhocks, and are there rust-resistant varieties of hollyhocks available? Brian Jonasson LaGrande, OR

Answer: As far as I know, there are no rust-resistant varieties of hollyhock. And, unfortunately, there's no way to completely control this disease. To begin with, practice good sanitation by cleaning up old, dead stalks and leaves and destroy. Remove and destroy infected leaves as soon as you notice them. Many people grow hollyhocks as biennials; the plants grow foliage the first year, and flower the second season. By planting seeds each year you will get an annual show of flowers.
